The desktop level integration mini solid Tesla coil products, the first stage are made of PCB, abandon the traditional solenoid secondary Tesla coil, highly integrated, cleaner and safer.
The power supply is a DC power adapter, a set of power supply, no other accessories required, no grounding. Compared to the 220 grid into the tesla coil, it is more stable, and began to make a mains fans know, tesla coil into the utility of tesla power tube due to high pressure spikes easy to damage the power supply only 52 v dc, only the mains rectification after one 6, heat sink with a temperature control switch, the power also have over-current protection, music mode pulse width do the restrictions, multiple protection. The disadvantage is that there is no fan to dissipate heat (because the heat is very low), do not run for too long at maximum power to avoid too fast temperature control protection
Just twist an electric needle, plug it in, and experience the magic of palm lightning. Square wave music can be played to increase its playability
Handmade profit is low, there is no beautiful box.
The left knob controls the size of the arc and the twist of the pointer. The right knob controls the constant frequency and speeds up the spray arc frequency clockwise.
Switch dialing for constant frequency mode, knob can adjust arc frequency and size
Intermediate pause of switch
Switch to music mode, and use audio cable to link the phone’s sound to the maximum playback. The knob can adjust the arc size
The Tesla coil is only powered by 52V DC. The low-voltage power supply ensures safety, and the effect is comparable to that of the desktop electric half-bridge Tesla coil.
The high-frequency secondary of 2M will not cause much pain even if the arc is touched by hand. At low frequencies, the electric arc can be played between the palms of the hands at will. The frequency of music mode is relatively high. When the electric arc is concentrated at a point, there will be a burning sensation.
